Return to Flight 370: The expired battery theory

The oddities and strange activity surrounding the vanishing Malaysian flight 370 only got weirder--again--today.. This breaking news report was carried by CNN but global sources also report:

The battery for the locator beacon of the flight data recorder of Malaysia Airlines Flight 370 expired more than a year before the plane's disappearance, an interim report on the investigation said Sunday, citing maintenance records.

The report said that there was no evidence to suggest the battery was replaced and that while such a battery can operate past its expiry date, "it is not guaranteed that it will work or that it would meet the 30-day minimum requirement."

The battery on the plane's other so-called black box, the cockpit voice recorder, was replaced as scheduled and remained within its expiry date, the report said.

A riddle solved? The reason we can't find a plane? Or a black box signified a reason for treason and a mass conspiracy that started a year prior?
